Substituent-tuned structure and luminescence sensitizing towards Al³⁺ based on phenoxy bridged dinuclear Eu^III complexes

Abstract

We present herein a novel luminescent enhanced EuIII complex-supported chemosensor by fine tuning the substitution group on ligands.

“…Yield: 81.6%. Mp: 132-134 • C. 1 H NMR (400 MHz, CDCl 3 ) δ 3.87 (s, 6H), 4.46 (s, 4H), 6.81 (dd, J = 7.9, 1.9 Hz, 2H), 6.86 (t, J = 7.9 Hz, 2H), 6.95 (dd, J = 7.9, 1.9 Hz, 2H), 8.23 (s, 2H), 9.70 (s, 2H). 13…”

“…Salen-like (N,N-bis(salicylidene)ethylenediamine) N 2 O 2 compounds are a class of the most versatile multidentate chelating ligands and could form stable mono-or multi-nuclear metal coordination compounds with alkaline earth, rare earth, and d-block transition metal ions [1][2][3][4][5][6][7][8][9]. Salen-like ligands and their corresponding metal coordination compounds have been proverbially studied in recent decades [10][11][12][13][14][15][16], these metal coordination compounds are used as precursors to obtain a great deal of oligometallic coordination compounds own to the high coordination abilities [17][18][19][20][21].…”

Syntheses, structural characterizations, and electrochemical and fluorescent properties of homo‐ and hetero‐polynuclear transition metal(II) complexes

“…In the past few decades, salen‐type ligands and their transition metal complexes have been studied exhaustively in modern coordination chemistry, which can be applied in obtaining optical and magnetic materials, in electrochemical and biological fields, in ion recognition, for supramolecular structures, and so forth.…”

Unprecedented Hexanuclear Cobalt(II) Nonsymmetrical Salamo-Based Coordination Compound: Synthesis, Crystal Structure, and Photophysical Properties

“…Salen (N,N -Disalicylideneethylenediamine) and its derivatives play an important role in inorganic chemistry [1][2][3][4][5][6][7][8][9][10], which are gained via the condensation reaction of diamines with salicylaldehyde or its analogues, and can coordinate to transition metal ions in a tetradentate chelating mode to form a neutral metal coordination compound [11][12][13][14][15][16][17][18]. Such coordination compounds have been extensively investigated as nonlinear optical materials [19], catalysts [20,21], strong activities with DNA, and so on [22][23][24][25][26][27][28][29].…”
